Some methods [1]}, [2]}, [3]} adopt a patch-based alignment procedure to extract detail from reference images via local matching.
In addition to the pixel space, this can also be done on image gradients [1]} and semantic features from CNNs [3]}, [6]}, [7]}.
These prior works are restricted to super-resolution and operate on single images, not videos.
SuperTran is aimed at improving upon video enhancement with aid from reference imagery.
